Good surprise or bad surprise? How does it compare to the 950/960M everyone was predicting?
how's AMD's driver support nowadays? haven't owned a notebook w one in a while. i have a Razer Blade also with a 970m, and i get constant updates from Nvidia. actually just got the update for Witcher 3 support yesterday.
AMD's OS X drivers are like NVIDIA drivers for Windows, while NVIDIA drivers for OS X are like AMD drivers on Windows.
They say 1.5 - 1.7 times (in other words 50-70% performance increase) on the Apple website in games. But who knows how they tested that. I doubt it was under windows with the newest drivers for both.
Testing conducted by Apple in April 2015 using preproduction 2.5GHz quad-core Intel Core i7based 15-inch MacBook Pro systems with AMD Radeon R9 M370X and 2GB of graphics memory, and shipping 2.5GHz quad-core Intel Core i7based 15-inch MacBook Pro systems with NVIDIA GeForce GT 750M and 2GB of graphics memory, all configured with 16GB of RAM. Resolution used: 1440 by 900. Tomb Raider tested using the built-in benchmark, with anti-aliasing turned off and low graphics quality. Formula 1 2013 tested using the built-in benchmark, with 2x anti-aliasing and default graphics settings. Batman: Arkham City GOTY tested using the built-in benchmark, with 4x anti-aliasing and high quality setting.
It'll certainly be in OS X. There are some details in the footnote:
